Suzuki hasn't listed the 2017 1st to 6th gear ratio's, but have said the 2017 uses the "previous model’s internal ratios" ie... 2016 1st to 6th gear ratio's.

Suzuki has listed the 2017 Primary and Final reduction ratio's as follows.

Primary Reduction ratio 1.652 (76/46)

Final Reduction ratio 2.647 (45/17)

New rear tyre size for 2017 190/55...

 

internal gear ratios are the same as l6 bike at least in the gear box, have not checked primary reduction.

i have just done this as to see the difference to stock L7 bike and L6 yoshi box in my old bike.

but again the rations are the same in both l6 and l7 bikes
